LNAV

----

The log file navigator, lnav, is an enhanced log file viewer that

takes advantage of any semantic information that can be gleaned from

the files being viewed, such as timestamps and log levels.  Using this

extra semantic information, lnav can do things like interleaving

messages from different files, generate histograms of messages over

time, and providing hotkeys for navigating through the file.  It is

hoped that these features will allow the user to quickly and

efficiently zero in on problems.

PREREQUISITES

-------------

The following software packages are required to build/run lnav:

  gcc/clang - A C++14-compatible compiler.

  libpcre2  - The Perl Compatible Regular Expression v2 (PCRE2) library.

  sqlite    - The SQLite database engine.  Version 3.9.0 or higher is required.

  ncurses   - The ncurses text UI library.

  readline  - The readline line editing library.

  zlib      - The zlib compression library.

  bz2       - The bzip2 compression library.

  re2c      - The re2c scanner generator.

  libcurl   - The cURL library for downloading files from URLs.  Version

              7.23.0 or higher is required.

  libarchive - The libarchive library for opening archive files, like zip/tgz.

  wireshark - The 'tshark' program is used to interpret pcap files.

INSTALLATION

------------

Lnav follows the usual GNU style for configuring and installing software:

Run "./autogen.sh" if compiling from a cloned repository.

  $ ./configure

  $ make

  $ sudo make install

USING

-----

The only file installed is the executable, "lnav".  You can execute it

with no arguments to view the default set of files:

  $ lnav

You can view all the syslog messages by running:

  $ lnav /var/log/messages*
